Subject: [PATCH 06/22] perf stat: Make stats work over the thread dimension
Date: Fri, 26 Jun 2015 11:29:11 +0200	[thread overview]
Message-ID: <1435310967-14570-7-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1435310967-14570-1-git-send-email-jolsa@kernel.org>

Now that we have space for thread dimension counts,
let's store it.
